IMPROVEMENT IN PUMPS.

TheV Schedule refen-ed to in these Letters Patent and making paxt of the same.

To all whom tt may concern Be it known that I, HENRY K. Kanyon, of Steubenville, in the county of Jefferson and State of Ohio, have invented a new and usefullmprovement in Deep-Vell Pumps; and I do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawing making a\part of this specification, in whichj Y Figure 1 is an outside View of my improved pump, as seen when inclosed in a case Figure 2 is a-like view ofthe same without the case;

Figure 3 is a sectional view, as formed by a plane passing through the pump in the line a: x, fig. 2;

Figure 4 is a like view, as formed by a vertical plane at right angles to the plane of section of fig. 3, or, in other words, a sectional view' of the pump through the line :vl x1, iig. 3;

Figure 5 is an elevation ot' the column of valves;

Figure (i shows a cross-section of the pump through the line x2 :112; and i Figure 7, hy a like sectional view, illustrates av modiu'cation ot' the construction.

Like letters of reference indicate like parts in each.

My invention relates to an improvement in that,

class of' pumps which throw or eject a stream of liquid at both the up-and-down strokes of the pis- 1 ton.

While useful for pumping purposes generally, itA

is especially designed for deep wells of a comparatively small bore.

`In suoli we1ls,' on account, of its compactness, it can he easily operated; and, ou account of its durability and non-liability to get outl ot' order, yit is, as an improvement, especially valuable, since it will seldom require removal.

By sucking and ejecting continuously it secures the largest possible yield of oil, water, or other liquid which can be pumped from the well.

To enable others skilled in the art to make and use myjmprovement, I will proceed to describe'its con.- struction and mode of operation.

In the drawing- A represents the working-barrel, which is connected with the tubing A above in Athe usual or any known lway.

Extending.,longitudinally along the outer face of this working-barrel is a series of' chambers, indicated by Nos. 1, 2,1 3, and 4, each formed 'by a seg.- me'nt or longitudinal section of a pipe, or a metallic U-shaped trough made solid with the Vworking-barrel A, or brazed or soldered on; or such chambers may consist of pipes crescent-shaped in cross-section, and soldered or brazed on, as illustrated in iig'. 7.

Each of these chambers has an opening, s, at `each vor either end, through-which it may be cleaned.

When the pump is in operation such openings are closed by collars t screwed down to cover them, with packing 1* interposed, if' so desired or found necessar v rIhe working-barrel A is connected with the chandhers. Nos. 1, 2, 3, and 4, by an' arrangement of ports, presently to be explained.

In the arrangement of the chambers Nos. 1 and 3 are diametrieally opposite each other, as also are Nos. 2 and 4.

In or near the lower end of the working-barrel A is a series or column of ball-valves, indicated by Nos. 1, 2, 3, and 4, numberingr from the highest one downf ward. These valves arc of the usual or any known construction.

-f'lhe cages a', in which the balls x1 are seated, g. 5, are rigidly connected together by stems x, with this addition, that a diaphragm or cago, z, is arranged in the column between valves Nos. 2 and 3.

This cage z has no passage through it vertically for the flow of' oil or water, and consequently the valves and valve-chambers above are cut oli" by it from direct communication with those below.

The hars z', however, just below valve No. 2, leave sufficient openings for the' dow of the liquid upward through valve No. 2, as presently to be explained.

The body of each valve-cage a, of the. valveless cage z, is packed by a leather ring, 1*', or,by a leather cup, or in other known manner.

For convenience of description I shall describe each valve-cage and ball as constituting a valve, and indicate it by its appropriate number. l

A stem, a?, connects valve No. 1 with a solid head, b', which is also packed, as described.

This head b', with ther valves Nos. 1 and 2, cage z, valves N os. 3 and 4, connecting stems and bars, constitute a series or column', which is firmly seated on a shoulder, c, or is otherwise supported against a downward motion in the lower end of the working-barrel A,:and ts securely in or isfastened in any known manner so that, by the operation of the piston, it will not be lifted from its seat.

' While the pump. is in voperation the column of' valves is stationary, but still it shouldbe removable ,for cleaning, repairs, or renewal. For ordinary usethe packing-rings r will hold it in place sucient-ly secure.

When the valves are thus in place a series'of chambers is formed; the upper one, a, between the head and alsothe body .through valve No,

ling-box, 11 with suitable packing inside and outside,

through which plays vthe piston-stem c', which latter carries at its lower end a` solid pump-piston or plunger, c, of any suitable or known construction.

The part of the working-barrel A in which the piston c operates I call the pumping-chamber w. From the upper part of this pumping-chamber w, just below the stuing-box, a port, d, fig. 3, opens into chamber No. 1.

Another port, d', opens from chamber No. 1 into' the annular chamber al, between valves Nos. land 2.

From the chamber a2, between valve No. 2 and cage z, another port, c', fig. 4, opens into side chamber No. 4, th'e lower endet' which, by a port, e, communicates `with the suction-pipe B.

Just above valve No. 1, and under the headb, a port, 'm, opens into chamber No. 4, and the upper end of chamber No. 4 opens, by a port, on', into the tubing above the stung-box b.

A close diaphragm or partition, g, is arranged across the chamber No. 4, between the ports m and e'.

Also, there is a port, n, just above the head b', which port opens into chamber No.2, and further down, leading fromthe same chamber, No. 2, to the annular chamber c, between valves Nos.j3 and 4, is a port, n.

Fromthe annular chamber a, Iig. 3, between valve No. 3 and the cage fz, another port, o, opens into chamber No. 3, and at the upper end of this chamber an additional port, o', opens into the tubing above the stuffing-box la. a

' Uperction.

into and up chamber No. 4; through port 'c' into annular chamber a?, between cage z and valve No. 2; through valve No. 2, thence tln'ongh port d', iig. 3, into and up chamber No. 1 5 and through port d into the pumping-chamber w, which it fills by the time the piston c reaches Lthe end'of the down stroke.

Second, ejecting action of the np stroke.

The tluid is forced out of tl e damping-chamberw, at the port d by which it enteredl down the chamber No. 1'; through port d' into the annular chamber a, between valvesNos. 1 and 2, by which valve No. 2 is closed and valve No. 1 is opened, whence it passes up 1, out through the port m, iig. 4, into chamber No. 4; up chamber No. 4, through `the port m into the tubing A', above stutting-box b, and, of course, up the tubing and out at the mout-h of the well.

Third,-sucking` action at the up stroke.

Its tendency then is to produce a vacuum under the piston c aud betweenit and the headb'. Under such pressure the fluid flows up the suction-pipe Bthrough valve No. 4, through annular chamber a and port n', iig. 4, into chamber No. 2; up chamber No.y 2, to and through port ajust above the head b', by which it fills the chamber 'w when the piston c has reached the end of its 11p-stroke.

Fourth, ejecting action atV theidown'strohe.

Tne fluid is forced ont of chamber fw by the same port n through which it enteredtdown the chamber No. 2, throughthe port u', into the annular chamber ci, where the force exert-ed through it closes valve No. 4, opens valve No. 3, passes up through it into the annular chamber a, ont through the port o, fig. 3, into the chamber No. 3; up this chamber, and out through the port o'nto the tubing above the stungbox b.

. Instead of the ball-valves, (thoughI consider them the best,) other suitable formsof valves may be used. Instead of connecting the valves by single stems, other suitable open connection may be made, such as that which unites the cage-body z to the valve N o. 2. Such connections should be made, so as to leave room for the oil to fiow through either valve, and to ow through a port or ports leading to the side chamber or chambers, as may be desired; or the valves may be made separately `and seated separately in the working-barrel, the arrangement remaining the saine'. Also, the side chambers, Nos. 1, 2, 3, and 4, may each consist of a complete .instead ot' a segmental or crescent-shaped pipe, and any suitable port-connection be made from each ot them tothe working-barrel, the arrangement ot' the ports, however, in such case, remaining substantially the same. The valves are readthreaded piu into the upper end ot' the head b and drawing all out at once, or, it" put in and seated separately, they-may be drawn out separately in the same way.

In manufacturing I sometimes rind it best to make the side chamber, Nos. 1, 2, 3, and 4, of very light metal, and in such case, to prevent them frombecoming. dented, collapsing,"r"`other like injury,.I`cover which I secure inplace by flanged nuts l. .The pump vcan then be handled, transported, put in and taken out of the well with much less liability ot' its'being injured, and there is little or no increase of expense. IVhat I claim as my invention, and desire to secure by Letters Patent, -is- 1. The construction of pumping tubes, by combining with the working-barrel a series if segmental orV U-shaped pipes, or a series of crescent-shaped pipes, either made as a part ot the working-barrel or securely attached thereto, and with an arrangement of communicating ports for the inflow and outflow ot the liquid, substantially as described.l

2. A series or column of' valves, four or more in number, arranged in the lower end of the workingbarrel, stationary when the pump is in operation, in combination with a corresponding series ot' longitud- 'inal side chambers with communicating ports, substantially as described.

3. A series or column of valves, Nos. 1, 2, 3, and 4, in combination with the head 7J', diaphragm or cagebody z, and chambers c 'a1 a2 a" a,`substantially as described.

YON, have hereunto set my hand.
